Problems solved by technology

[0004] Usually, the plastic parts on the car are often scratched, which not only affects the overall appearance of the car, but also is not easy to repair. It is usually maintained by replacing parts, which increases the cost investment. How to develop a scratch-resistant injection molding material is a must. Important technical problems urgently needed to be solved by those skilled in the art

Embodiment Construction

[0025] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0026] A scratch-resistant injection molding material, wherein the scratch-resistant injection molding material comprises by mass percentage:

[0027]

[0028] In this case, the plasticizer is selected from one or more of phthalates, aliphatic dibasic acid esters, phosphoric acid esters, and chlorinated paraffin; the dispersant is triethylhexyl phosphoric acid, lauryl sulfuric acid One or two mixtures of sodium and methyl amyl alcohol; lubricants are selected from one or more of silicone oil, fatty acid, amide, polyester, synthetic ester, and carboxylic acid; the components of the anti-scratch agent are in mass percentage The calculation includes (taking the overall scratch-resistant agent as a reference):

[0029]

[0030] Wherein, in this case, each component of the scratch-resistant agent preferably includes by...

Abstract

The invention discloses a scratch-resistant injection material. The scratch-resistant injection material is characterized by comprising the following components by mass percent: 36-41 percent of polycarbonate, 23-28 percent of wood pellets, 10-14 percent of plasticizer, 6-9 percent of scratch-resistant agent, 16-19 percent of calcium carbonate, 5-6 percent of dispersant and 3-6 percent of lubricant. Parts produced by using the injection material have better scratch-resistant performance, the entire shapes of the parts are kept, the possibility of frequently replacing the parts due to scratching by users is reduced, and therefore the cost input is reduced.

Description

technical field [0001] The invention relates to an injection molding material, in particular to an injection molding material with scratch resistance. Background technique [0002] With the development of technology and the change of people's ideas, many non-metal parts appear in auto parts. Among them, the dominant material of non-metal parts is plastic parts, which are easy to process, easy to install and light to use, so they are more and more favored by the automobile industry. The use of plastic parts is an inevitable requirement for the future development of automobiles. [0003] The so-called injection molding (injection molding) refers to the method of injecting heated and melted materials into the mold, cooling and solidifying, and obtaining molded products. The specific process is that the granular or powdery plastic is fed from the hopper of the injection molding machine into the heated barrel, heated and plasticized into a molten state, and then injected into th...
